1. General description
2. Features
2.1 General
2.2 AM
The TEA5777 is a BiCMOS single-chip (32-pin or 48-pin package), electronically tuned
AM/FM stereo radio circuit, with fully integrated IF selectivity and demodulation including
local synthesized oscillator, and is intended to be used in electronically tuned radio sets.
In FM mode the radio is completely alignment free and in AM mode only a minimum of
antenna input alignment is required. The radio requires a minimum number of small and
low cost external components.
The IC communicates with a microcontroller via the I

TEA5777
Low-power AM/FM stereo radio for handheld applications
Rev. 01 — 11 April 2006
High integration level of the AM and FM receiver means a very limited number of
external components are required
On-board PLL synthesizer tuning function which includes VCOs, dividers, phase
detectors and charge pump
FM mixer conversion for US and Europe, OIRT and Japanese band to IF
Crystal reference frequency oscillator operating at 4 MHz
External reference input frequency of 13 MHz (bus selectable)
Autonomous search function
IF counter with 1-bit output via the bus
Silent readout of mono or stereo information and IF in-window indication
Level detector with 4-bit level information output via the bus
I
Standby mode switched via the bus
2 software programmable I/O ports with multiple functions
Supply voltage range: 2.7 V to 7 V (typical 3 V)
